shaft which winds the package by surface contact therewith, is driven ata constant speed and in which the traverse guide actuating cam shaft isdriven at varying speeds, utilizing a member mounted to oscillate aboutthe cam shaft, said oscillating member being connected to a crankmemberdriven by the cam shaft, the cam shaft in turn bein driven 'by thewinding roll shaft through t e oscillating member.

My invention more specifically comprises a reduction gearing connectingthe winding roll shaft with the cam shaft and a second reduction gearingconnecting the cam shaft with the crank member so'thata very slowmovement is imparted to the oscillating memher which carries a portionof the reduction .gearing between the winding roll shaft and the camshaft. One embodiment of my invention also contemplates the use of ayielding connection between the crank member and the oscillating member,said yielding connection acting as a Y shock absorber for reducing theshock on the gears incident to the operation of the wind' ing mechanism.

Practical embodiments of my invention are represented in theaccompanying drawings, in which v i Fig. '1 represents a detail sideview of a winding machine with one embodiment of my improved drivingmechanism applied thereto. Fig. 2 represents an end view of the same. 4Fig. 3 represents a detail section taken in the plane of the lineIII-III of Fig. 1, looking in the direction of the arrows with the OS-cillating member in another position from that shown in Figs. 1 and 2.

Fig. 4 represents a detail side view ofa winding machine with anotherembodiment the plane of the line VI-VI of Fig. looking in the directionof the arrows with the-oscillating member in another position from thatshown in Figs. 4 and 5.

In both embodiments the winding machine frame is denoted by 1 and inthis frame are rotatably mounted the winding roll shaft 2, the traverseguide actuating cam shaft 3 and the yoke oscillating crank shaft 4. Theyoke 5 freely swings on the cam shaft 3 and is oscillated by the crankshaft 4, through a connecting rod 6.

The winding roll shaft 2 is driven at a constant speed from the motor 7,through the gears 8 and 9 fast on the motor shaft and the winding rollshaft-respectively.

The cam shaft 3 is driven from the winding roll shaft 2 through .a trainof reduction gearing which includes a gear 10 fast onthe winding rollshaft, a pair of reduction idler gears 11 and 12 loosely mounted on thecam shaft 3 and connected for rotation together, a pair of reductionidler gears 13 and 14 carried by the oscillating yoke 5 and connectedfor rotation together, and a gear 15 fast on the cam shaft 3.

In the embodiment illustrated in Figs. 1 to 3 inclusive, the yokeoscillating crank shaft 4 is driven from the cam shaft 3 through areduction gearing which includes a bevel gear 16 meshing with a bevelgear 17 carried by the upper end of a vertical shaft 18. the lower endof which shaft is provided with a worm 19 which meshes with a worm gear20 carried by thecrank shaft 4.-

In the embodiment illustrated in Figs-4 to 6 inclusive, the yokeoscillating crank shaft 4 is driven from the cam shaft 3 through a reduction gearing which includes a gear 21 fast on the cam shaft, a'pairof reduction idler gears 22 and 23 rotatably mounted on the axle 24, anda gear 25 fast on the crank shaft.\

To'lessen the shock on the gearing, due to the oscillation of the yoke 5by the crank shaft ,4, I yieldingly connect the connecting rod 6 to theyoke 5, in the present instance by providing the connecting rod with anelongated slot 26, through which a pin 27 on the yoke passes, a tensionspring 28 having one end attached to said pin and the other end attachedto the connecting rod.

From the above description it will be seen that by driving the cam shaftthrough gears on an oscillating member, said member being oscillated bya crank shaft driven from the cam shaft. the cam shaft is driven atvarying speeds. This is accomplished by reason of the fact that when theyoke 5 swings in the same direction as gear 11 revolves, the speed ofgear 15 is reduced, and when the yoke is swung in the opposite directionthe speed of gear 15 is increased. It will also be seen that by drivingthe cam shaft at varying speeds, the tendency of the yarn to lay oneturn upon a preceding turn is eliminated and the so called ribbon windis broken up. The formation of undesirable lumps or protuberances in thewound package is also eliminated.

It is evident that various changes may be resorted to in theconstruction, form and arrangement of the several parts withoutdeparting from the spirit and scope of my invention; and hence, I do notintend to be limited to the particular embodiment herein shown anddescribed, but
